WELL AND ROCKDRILLING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 247,192, dated September20, 1881. Application filed March 15, 1881. (No model.)

To all whom it may concern:

Be it known that I, ELIAS J. HILL, a citizen of the United States,residing at Findlay, in the county of Hancock and State of Ohio, haveinvented certain new and useful Improvements in Well and Rock DrillingMachines; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing bad to the accompanying drawings, and to letters or figures ofreference marked thereon, which form a part of this specification.

The object of this invention is to impartboth a rotary and a verticalmovement to the drillshaft in a machine for drilling wells and rocks.

The improvement consists, first, in the combination, with thedrill-shaft provided with a lantern-wheel, rigid thereon, of a rotarygear engaging the lantern-wheel, a pair of collars or stops adj ustablysecured upon the drillshaft, a pivoted lever having one end arrangedbetween said stops or collars, and a set of camarms upon thedriving-shaft arranged to act at intervals upon the lever, whereby theaction of the cam-arms will cause the lever to raise the drill-shaft,and the adjustment of the said collars determines the heightto which theshaft is elevated; second, in the combination, with the drill-shaftprovided with a lantern-Wheel, rigid thereon, of a rotary gear engagingthe lantern-wheel, a shaft provided with a bandpulley and with a gearintermeshin g with said gear that acts upon the lantern-wheel, a collarupon the drill-shaft, a pivoted lever with one end arranged to actagainst the under side of said collar, a set of cam-arms upon thedrivingshaft, arranged to act upon and depress the opposite arm ofthe-lever, and belt-connection between the driving-shaft and theband-wheel upon the shaft carrying the gear before specified, all ashereinafter more fully described.

In the drawings, Figure 1 is a side elevation of a drilling-machineconstructed in accordance with my improvement, a portion of thederrick-frame being broken away; and Fig. 2 is a top or plan view of theoperative parts of my improvement.

A indicates a suitably-constructed derrickframe, and B the verticaldrill-shaft, which will be provided with a bit, O, in the usual way.

D refers to the lever that is pivoted between standards E, the saidstandards being either formed with or secured to base-plates E E. Oneend of this lever is bifurcated and its prongs extended so as to embracethe shaft B between two stops or collars, a a, which are adjustablysecured upon the said shaft by means of set-screws.

K indicates the balance-wheel upon the driving-shaft, and P a set ofcam-arms, arranged upon said shaft to act upon and depress at intervalsone of the arms of the pivoted lever.

Upon the drill-shaft is secured a lanternwheel, B, by means ofset-screws, or in any other suitable way; and upon the frame of thederrick is mounted a rotary gear-wheel, H, which engages the verticalbars of the lanternwheel. A smaller gear-wheel, h, upon a horizontal"shaft engages the gear-wheel H, motion being imparted to said shaft bybelt-connection between a pulley, G, upon the shaft and a band-wheel, K,upon the driving-shaft l. The drill-shaft passes through suitableguides, one of which, 0, is arranged below the collars a upon the shaft,as illustrated in Fig. 1. Dur- 1ng the rotation of the driving-shaft arotary motion istransmitted to the drill-shaft through the medium of thebelt and gear-wheels, and at the same time the drill-shaft will besuccessively raised and allowed to drop, through the agency of thecam-arms, pivoted lever, and the upper collar upon said drill-shaft, inthe following manner: As one of the cam-arms P, strikes the lever thearm of the lever adjacent to said cam will be depressed, and hence theother lever-arm will be raised so as to act against the upper one of thecollars a, and

thereby raise the drill-shaft. The cam-arm then trips the lever, so asto allow the drillshaft to descend by gravity. The dotted lines in Fig.1 represent the position of the several parts when the drill-shaft isthus raised, it being evident that the employment of the lantern-wheelwill admit of the up-and-down movement of the drill-shaft at the sametime that it is being rotated, by reason of the action of the rotarygear upon the lantern-wheel.

By raising either both of the collars or the upper collar alone theheight to which the lever will raise the drill-shaft will be determined.

Havingdescribedmyinventiomwhatlclaim, and desire to secure by LettersPatent, is

1. The combination, with the drill-shaft provided with a lantern-wheel,rigid thereon; of a rotary gear engaging the lanternwheel, a shaftprovided with a band-pulley and with a gear intermeshing with the rotarygear that acts upon the lantern-Wheel, a collar upon the drill-shaft ata point below the lantern-wheel, a pivoted lever having one end arrangedto act against the under side of said collar, a set of cam-arms upon thedriving-shaft arranged to act upon and depress one end of the pivotedlever, and belt-connection between the driving-shaft and band-wheel uponthe shaft carrying the gear h, substantially as described.
